Description

【0001】
【発明の属する技術分野】
この発明は半導体ウエハを保管や輸送する際に使用する半導体ウエハ包装容器に関する。
【0002】
【従来の技術】
従来集積回路などに使用する半導体ウエハは、シリコン単結晶よりなるインゴットを薄くスライスすることにより製作されており、外力に対して破損しやすい性質を持っている。
【0003】
また半導体ウエハを保管したり、輸送する場合、保管中や輸送中に破損したり、汚損するのを防止するため、半導体ウエハを容器に収容しており、収容するための容器も種々提案されている。
【0004】
例えば特開平7−14913号公報には、上面が開口する本体ケースと、この本体ケース内に収容され、かつ複数の半導体ウエハが互に接触しないように間隔を存して支持する多数のウエハ支持溝を有するウエハキャリアと、上記本体ケースの上面開口部を密封する蓋部と、この蓋部の内側に着脱自在に取付けられ、かつ上記ウエハ支持溝に支持された半導体ウエハを上方より押圧する押圧体と、上記蓋部の4辺にそれぞれ設けられた4個のクリップを有する半導体ウエハ包装容器が記載されている。
【0005】
また特開平8−255826号公報には、半導体ウエハ収納容器を構成する、上蓋、容体、内箱、上部および下部緩衝板の内のいずれか、または2以上の部材間に伸縮性膜を張設し、この伸縮性膜に半導体ウエハの周縁部の少なくとも一点を接触させることで、半導体ウエハを容器内に支持するようにした半導体ウエハ−収納容器が記載されている。
【0006】
【発明が解決しようとする課題】
しかし前者公報の半導体ウエハ包装容器では、蓋部の4辺にそれぞれ設けられたクリップを本体ケース側に係止する構造のため、これらクリップを開閉する場合、全てのクリップを同時に開閉することは困難である。
また蓋部は気密を保持するためのガスケットの弾性により押し上げられているため、クリップを外す場合、一方の手で蓋部を下方向へ押し付けながら、他方の手で4個のクリップを順次外す操作が必要となり、クリップの開閉操作が面倒である上、各クリップには、それぞれ2個所の係止部が設けられているため、一方の係止部が外れても、他方の係止部が外れないことがよくあり、クリップの開閉操作に時間がかかるなどの不具合もある。
【0007】
またウエハキャリヤと押圧板により半導体ウエハの周辺部4点を支持する構造のため、ウエハキャリヤ及び押圧板と半導体体ウエハとの接触面積が多く、このため輸送中半導体ウエハのガタツキにより接触面が摩耗し、発塵の原因となる不具合もある。
【0008】
一方後者公報の半導体ウエハ収納容器では、伸縮性膜で半導体ウエハの外縁部を押し付けて半導体ウエハを容器内に支持する構造のため、半導体ウエハには常に伸縮性膜の弾性による押付け力が作用しており、その結果半導体ウエハに応力歪が発生して、半導体ウエハが変形するなどの不具合がある。
【0009】
この発明はかかる従来の不具合を改善するためになされたもので、半導体ウエハを破損や汚損することなく保管や輸送ができ、かつカバーの開閉も容易な半導体ウエハ包装容器を提供することを目的とするものである。
【0010】
【課題を解決するための手段】
上記目的を達成するため請求項1記載の発明は、上面に開口部を有し、かつ両側部に係止片が突設されたボトムケースと、上記ボトムケース内に着脱自在に収容され、かつ互に対向する面に、半導体ウエハを収容する多数のウエハ支持溝が縦方向に形成されたウエハキャリヤと、上記ボトムケースの開口部に着脱自在に取付けられ、かつ両側部に、上記ボトムケースの係止片に係脱自在なクランプ部を有するとカバーと、上記カバーの内側上面に取付けられ、かつ上記ウエハ支持溝に収容された半導体ウエハの外周縁を下方へ押圧するウエハ押圧部材を有するクッション部材とを具備した構成とし、上記クッション部材のウエハ押圧部材近傍に、半導体ウエハに形成されたオリフラに当接して、半導体ウエハの回転を阻止する鋸歯状のウエハ支持溝を有する開脚部を設け、上記ウエハ押圧部材をカバーの内側上面に取付けるリブの一部に、上記開脚部の変形を防止する補強リブを突設すると共に、上記クッション部材のウエハ押圧部材を各ウエハ支持溝毎に分岐して、分岐されたウエハ押圧部材の根元部分を薄肉な連結部で連結したものである。
【0011】
上記構成により、ウエハキャリヤのウエハ支持溝に半導体ウエハを収容して、ボトムケースの開口部にカバーを嵌合すると、カバー内側に設けられたクッション部材のウエハ押圧部材が、各半導体ウエハの外周面に当接して半導体ウエハを上方より押圧するため、輸送中半導体ウエハがウエハ支持溝内でガタつくことがない。さらに、ウエハ支持溝内で半導体ウエハが回転するのを防止することができると共に、半導体ウエハに大きな回転力が作用しても、開脚部が変形するのを補強リブが阻止するため、オリフラ部分がウエハ支持溝を乗り越えることがない。また、ウエハ押圧部材のクリープによる弾性力の低下を防止することができると共に、ウエハ押圧部材の根元部分に加わる応力を連結部が分散させるため、応力集中によりウエハ押圧部材が根元部分より折損する心配もない。
【0020】
【発明の実施の形態】
この発明の実施の形態を図面を参照して詳述する。
図1は半導体ウエハ包装容器の正面図、図2は同側面図、図3は図1のA−A線に沿う断面図、図4は図2のB−B線に沿う断面図、図5は図1のC−C線に沿う断面図、図6は分解斜視図、図7は図6のD方向からの矢視図、図8は図6のE−E線に沿う拡大断面図、図9は図4のF円の拡大図である。
【0021】
これら図においては1はボトムケース、2はガスケット、3はウエハキャリヤ、4はクッション部材、5は透明なカバーを示す。
上記ボトムケースは合成樹脂により上面が開口された箱形に成形されていて、開口部1aに、上記ガスケット2を収容する凹溝1bが形成されていると共に、両側面には、開口部1aよりやや下側に、下方へ向けて突設された舌片状の係止片1cが設けられている。
【0022】
またこれら係止片1cを除く外周部には下方へ屈曲されたスカート部1dが形成されていて、このスカート部1dの切欠部と係止片1cの両端部間には、上記カバー5に突設されたクランプ部5aの両側ガイド部5jが上方より嵌入する間隙1eが形成されている。
上記ガスケット2は、ボトムケース1の凹溝1bに上方より嵌合自在な角枠状となっていて、ゴムなどの弾性体により成形されており、図8の断面図で示すように、上方及び下方にリップ部2a,2bを有していて、下側のリップ部2bを凹溝1b内に嵌合すると、上側のリップ部2aが凹溝1b内より上方へ突出して、この上側のリップ部2aは、ボトムケース1の開口部1aを上方より閉鎖するカバー5の開口部5aに形成された凹溝5b内に嵌入するようになっている。
【0023】
上記ウエハキャリヤ3は、左右側板3aと、これら側板3aの一側間を連設する背面板3b及び他側のほぼ中央部間を連設する連結杆3cよりなり、ポリプロピレンなどの合成樹脂により一体成形されており、両側板3aの下部側は収容する半導体ウエハ10の外周形状に合せて内側へ湾曲されていると共に、下端部には上記ボトムケース1の内底面に突設された膨出部1fに上方より嵌合する脚部3dが形成されている。
【0024】
また上記両側板3aの対向面には、半導体ウエハ10を収容するための多数のウエハ支持溝3eが幅方向に等間隔に形成されており、これらウエハ支持溝3eは連結杆3cより上側がほぼ垂直に、そして下側は側板3aの湾曲に沿って半導体ウエハ10の外周面の曲率と一致するよう湾曲されている。
【0025】
一方上記クッション部材4は、カバー5の内側上面に突設された連続リブ5cと断続リブ5dの間の間隙5eに下方より嵌着される枠状部4aと、この枠状部4aの前後辺間に横架された互に平行する2本の横杆4bを有しており、各横杆4bは、カバー5の内側上面に突設された互に対をなす連続リブ5f間の間隙5gに下方より嵌着されるようになっている。
【0026】
上記クッション部材4の左右辺には、円弧状に湾曲し、かつ上下方向に弾性を有するウエハ押圧部材4cが2方向より互に対向するよう突設されている。
これらウエハ押圧部材4cは、上記ウエハキャリヤ3に形成されたウエハ支持溝3eと同じ間隔で分岐されていて、円弧状部4dと、この円弧状部4dの先端側にほぼ水平に形成された直線部4eよりなり、直線部4eの先端側下面には、半導体ウエハ10の外周縁に嵌合するV溝4fを有する押圧部4gが突設されていると共に、円弧状部4dの基端部間は薄肉な連結部4hにより互に連結されていて、直線部4eが振動や衝撃などによって横方向へずれるのを規制すると同時に、応力を分散させて、ウエハ押圧部材4cが折損するのを防止するようになっている。
【0027】
また上記クッション部材4の横杆4bの下縁は、ウエハ押圧部材4cの直線部4e方向へほぼハ字形に開脚されていて、この開脚部4iに鋸歯状のウエハ支持溝4jが形成されている。これらウエハ支持溝4jは、ウエハキャリヤ3のウエハ支持溝3eと同一間隔となっていて、ウエハ支持溝3e内に嵌挿された半導体ウエハ10のオルフラ10a部分が嵌入されるようになっている。
【0029】
一方ボトムケース1の開口部1aを閉鎖するカバー5は透明な樹脂により一体成形されていて、内側上面に上述した連続リブ5c,5fと断続リブ5dが突設されていると共に、クッション部材4の横杆4bが嵌合する連続リブ5fのうち、内側に位置する連続リブ5fには、これと直角に補強リブ4kが複数個所突設されていて、これら補強リブ4kによりクッション部材4の開脚部4hが変形するのを防止するようになっている共に、カバー5の両側には、クランプ部5aが下方へ向けて突設されている。
【0030】
上記クランプ部5aは、図2及び図6に示すように角板状をなしていて、開口縁部とほぼ同じ高さに、上記ボトムケース1に設けられた係止片1cよりやや大きな角孔状の係止孔5gが開口されており、ボトムケース1の開口部1aにカバー5を嵌合した際、係止孔5gの下縁が図9に示すようにボトムケース1の係止片1cに係合して、ボトムケース1にカバー5が係止できるようになっていると共に、クランプ部5aの内側には、ボトムケース1の開口部1aにカバー5を嵌合する際、ボトムケース1の係止片1c両端によりカバー5の位置決めを行うガイド突条5hがクランプ部5aの幅方向に離間して縦方向に2条突設されている。これにより、ボトムケース1の開口部1aにカバー5を嵌合する際、係止片1cの両端面にガイド突条5hがガイドされて、ボトムケース1に対してカバー5が位置決めされるため、ボトムケース1の所定位置にカバー5を精度よく嵌合することができると共に、カバー5を取外す際には、係止孔1cより係止片1cを指で押すことにより、係止片1cよりクランプ部5aを簡単に外すことができる。
【0031】
またカバー5の内面にも、ボトムケース1の開口部1aにカバー5を嵌合する際、ウエハキャリヤ3の上部外周面に摺接して、カバー5の位置決めを行う2条のガイドリブ5iが上下方向に突設されている。これにより、ボトムケース1の開口部1aにカバー5を嵌合する際、ウエハキャリヤ3の上部外周にガイドリブ5iが当接してボトムケース1に対してカバー5を位置決めするため、カバー5の位置決めが容易に行える。
【0032】
次に構成された半導体ウエハ包装容器の作用を説明すると、輸送や保管する半導体ウエハ10を収容するに当っては、カバー5のクランプ部5aをボトムケース1の係止片1cより外すが、このとき指で係止片1cを押しながら、クランプ部5aの下端を外側へ引張ることにより、係止片1cがクランプ部5aより外れるので、カバー5を簡単に取外すことができる。ボトムケース1よりカバー5を取外したら、ボトムケース1内に収容されているウエハキャリヤ3の各ウエハ支持溝3e内に上方より半導体ウエハ10を1枚づつ収容する。
【0033】
そして所定枚数の半導体ウエハ10を収容したら、再びボトムケース1の開口部1aをカバー5により閉鎖するが、閉鎖するに当っては、まずカバー1をボトムケース1の上方に位置させ、この状態でカバー5を下げると、カバー5内面に突設されたガイドリブ5iがボトムケース1内のウエハキャリヤ3の外周面に当接して、ボトムケース1に対してカバー5の1次位置決めが行われる。
【0034】
次にこの状態でカバー5をさらに下げると、カバー5のクランプ部5aがボトムケース1の係止片1cに達して、クランプ部5aの内側に突設されたガイド突条5hの間に係止片1cが位置するようになり、この状態でカバー5をさらに下げると、ガイド突条5hによりボトムケース1に対してカバー5の2次位置決めが行われるため、カバー5の内側に取付けられたクッション部材4の押圧部4gと、開脚部4iのウエハ支持溝3eの位置が正確に一致し、押圧部4gのV溝4fとウエハ支持溝4j内に半導体ウエハ10の外周縁及びオリフラ10a部分が嵌入される。
【0035】
この状態でさらにカバー5を下げると、クランプ部5aの係止孔5gにボトムケース1側の係止片1cが嵌合して、ボトムケース1に対してカバー5が係止されるが、このときもクランプ部5aの両側ガイド部5jがスカート部1dの間隙1eによりガイドされるため、ボトムケース1の開口部1aに対してカバー5を所定位置に正確に嵌合することができる。
【0036】
またカバー5が係止された状態では、クッション部材4のウエハ押圧部材4cの円弧状部4dの弾性により半導体ウエハ10はウエハ支持溝3eに押付けられているため、輸送中に加わる振動や衝突に対して半導体ウエハ10がガタつくことがないと共に、半導体ウエハ10に回転力が作用して、オリフラ10a部分が開脚部4iを変形させようとしても、補強リブ4kが開脚部4iの変形を阻止するため、オリフラ10a部分が開脚部4iを乗り越えて回転するのを防止することができる。
【0037】
【発明の効果】
この発明は以上詳述したように、カバーの両側に設けたクランプ部を外すだけでボトムケースよりカバーが取外せるため、カバーの脱着作業を容易に行えると共に、このときボトムケースがカバーとともに連れ上りすることがないため、操作も容易である。
またカバーを外す際には、クランプ部の係止孔より係止片を押しながらクランプ部を外側へ引張るだけでクランプ部が外れることから、クランプ部の取外しが短時間で容易に行えると共に、ボトムケースの開口部にカバーを嵌合する際、カバー内側に突設されたガイドリブと、クランプ部内面に突設されたガイド突条の少なくとも2個所でボトムケースに対してカバーが位置決めされるため、ボトムケースの所定位置に正確にカバーを嵌合することができる。
これによってボトムケースとカバーの間に隙間が発生することがないので、容器内の密閉が確実に行えるようになる。
さらにカバーの内側に設けたクッション部材のウエハ押圧部材により半導体ウエハの外周縁を上方より押圧するようにしたことから、輸送中に振動や衝撃が加わっても、半導体ウエハがガタつくことがないと共に、開脚部に設けられたウエハ支持溝に半導体ウエハのオリフラ部分を嵌合したことにより、輸送中に半導体ウエハが回転するのを防止することができるため、半導体ウエハが摩耗して、発塵の原因となるなどの心配もない。しかも半導体ウエハに大きな回転力が作用しても、補強リブが開脚部の変形を阻止するため、オリフラ部が開脚部を乗り越えて回転するなどの虞れもない。

BACKGROUND OF THE INVENTION
The present invention relates to a semiconductor wafer packaging container used for storing and transporting semiconductor wafers.
[0002]
[Prior art]
Conventionally, a semiconductor wafer used for an integrated circuit or the like is manufactured by thinly slicing an ingot made of a silicon single crystal, and has a property that it is easily damaged by an external force.
[0003]
Also, when storing or transporting semiconductor wafers, in order to prevent damage or contamination during storage or transportation, semiconductor wafers are stored in containers, and various containers for storing them have been proposed. Yes.
[0004]
For example, Japanese Patent Application Laid-Open No. 7-14913 discloses a main body case having an open upper surface and a number of wafer supports that are accommodated in the main body case and are spaced apart so that a plurality of semiconductor wafers do not contact each other. A wafer carrier having a groove, a lid portion that seals the upper surface opening of the main body case, and a pressing member that is detachably attached to the inside of the lid portion and that presses the semiconductor wafer supported by the wafer support groove from above. A semiconductor wafer packaging container having a body and four clips respectively provided on four sides of the lid is described.
[0005]
Japanese Patent Laid-Open No. 8-255826 discloses a stretchable film stretched between two or more members of an upper lid, a container, an inner box, an upper and a lower buffer plate constituting a semiconductor wafer storage container. In addition, a semiconductor wafer storage container is described in which at least one point on the peripheral edge of the semiconductor wafer is brought into contact with the stretchable film so that the semiconductor wafer is supported in the container.
[0006]
[Problems to be solved by the invention]
However, the semiconductor wafer packaging container disclosed in the former publication has a structure in which the clips provided on the four sides of the lid are respectively locked to the main body case side. Therefore, when opening and closing these clips, it is difficult to simultaneously open and close all the clips. It is.
In addition, the lid is pushed up by the elasticity of the gasket to keep it airtight, so when removing the clip, press the lid downward with one hand while removing the four clips with the other hand. Each clip is provided with two locking parts, so that even if one locking part comes off, the other locking part comes off. In many cases, there are also problems such as taking time to open and close the clip.
[0007]
In addition, because the wafer carrier and pressing plate support the four peripheral parts of the semiconductor wafer, the contact area between the wafer carrier and pressing plate and the semiconductor wafer is large, and the contact surface wears due to rattling of the semiconductor wafer during transportation. However, there is also a problem that causes dust generation.
[0008]
On the other hand, the semiconductor wafer storage container disclosed in the latter publication has a structure in which the outer edge of the semiconductor wafer is pressed by a stretchable film to support the semiconductor wafer in the container, so that the semiconductor wafer always receives a pressing force due to the elasticity of the stretchable film. As a result, there is a problem that stress strain occurs in the semiconductor wafer and the semiconductor wafer is deformed.
[0009]
The present invention was made to remedy such a conventional problem, and an object thereof is to provide a semiconductor wafer packaging container that can be stored and transported without damaging or fouling a semiconductor wafer, and that the cover can be easily opened and closed. To do.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the invention described in claim 1 includes a bottom case having an opening on the upper surface and protruding locking pieces on both sides, and is detachably accommodated in the bottom case, and A wafer carrier in which a plurality of wafer support grooves for accommodating semiconductor wafers are formed in the vertical direction on opposite surfaces, and is detachably attached to the opening of the bottom case, and on both sides of the bottom case. Cushion having a cover and a wafer pressing member that is attached to the inner upper surface of the cover and presses the outer peripheral edge of the semiconductor wafer accommodated in the wafer support groove downward when the engaging piece has a detachable clamp portion a structure that and a member, the wafer pressing member near the cushion member, in contact with the orientation flat formed on a semiconductor wafer, serrated wafer to prevent rotation of the semiconductor wafer An opening leg portion having a holding groove is provided, and a reinforcing rib for preventing deformation of the opening leg portion is protruded from a part of the rib for attaching the wafer pressing member to the inner upper surface of the cover, and the wafer pressing force of the cushion member The member is branched for each wafer support groove, and the base portion of the branched wafer pressing member is connected by a thin connecting portion .
[0011]
With the above configuration, when the semiconductor wafer is accommodated in the wafer support groove of the wafer carrier and the cover is fitted to the opening of the bottom case, the wafer pressing member of the cushion member provided on the inner side of the cover becomes the outer peripheral surface of each semiconductor wafer. Since the semiconductor wafer is pressed from above, the semiconductor wafer is not rattled in the wafer support groove during transportation. Further, the rotation of the semiconductor wafer in the wafer support groove can be prevented, and even if a large rotational force acts on the semiconductor wafer, the reinforcing rib prevents the opening leg portion from being deformed. Does not get over the wafer support groove. In addition, it is possible to prevent a decrease in elastic force due to the creep of the wafer pressing member and to disperse the stress applied to the root portion of the wafer pressing member, so that the wafer pressing member may break from the root portion due to stress concentration. Nor.

[0030]
The clamp portion 5a has a square plate shape as shown in FIGS. 2 and 6, and is a square hole slightly larger than the locking piece 1c provided on the bottom case 1 at substantially the same height as the opening edge. When the cover 5 is fitted into the opening 1a of the bottom case 1, the lower edge of the locking hole 5g is as shown in FIG. The cover 5 can be locked to the bottom case 1, and the bottom case 1 is fitted inside the clamp portion 5 a when the cover 5 is fitted into the opening 1 a of the bottom case 1. Two guide protrusions 5h for positioning the cover 5 at both ends of the locking piece 1c are provided in the vertical direction so as to be separated from each other in the width direction of the clamp portion 5a. Thereby, when the cover 5 is fitted into the opening 1a of the bottom case 1, the guide protrusion 5h is guided to both end surfaces of the locking piece 1c, and the cover 5 is positioned with respect to the bottom case 1. The cover 5 can be accurately fitted to a predetermined position of the bottom case 1, and when the cover 5 is removed, the locking piece 1c is pushed from the locking hole 1c with a finger to be clamped from the locking piece 1c. The part 5a can be easily removed.
[0031]
In addition, when the cover 5 is fitted into the opening 1 a of the bottom case 1 on the inner surface of the cover 5, two guide ribs 5 i that slide on the upper outer peripheral surface of the wafer carrier 3 to position the cover 5 are provided in the vertical direction. Projected to As a result, when the cover 5 is fitted into the opening 1 a of the bottom case 1, the guide rib 5 i comes into contact with the upper outer periphery of the wafer carrier 3 to position the cover 5 with respect to the bottom case 1. Easy to do.
[0032]
Next, the operation of the semiconductor wafer packaging container configured will be described. In order to accommodate the semiconductor wafer 10 to be transported or stored, the clamp portion 5a of the cover 5 is removed from the locking piece 1c of the bottom case 1. While pushing the locking piece 1c with a finger, the locking piece 1c is detached from the clamping portion 5a by pulling the lower end of the clamping portion 5a outward, so that the cover 5 can be easily removed. When the cover 5 is removed from the bottom case 1, the semiconductor wafers 10 are accommodated one by one in the respective wafer support grooves 3 e of the wafer carrier 3 accommodated in the bottom case 1.
[0033]
When the predetermined number of semiconductor wafers 10 are accommodated, the opening 1a of the bottom case 1 is again closed by the cover 5. In closing, the cover 1 is first positioned above the bottom case 1 and in this state. When the cover 5 is lowered, the guide rib 5 i protruding from the inner surface of the cover 5 comes into contact with the outer peripheral surface of the wafer carrier 3 in the bottom case 1, and primary positioning of the cover 5 with respect to the bottom case 1 is performed.
[0034]
Next, when the cover 5 is further lowered in this state, the clamp portion 5a of the cover 5 reaches the locking piece 1c of the bottom case 1, and is locked between the guide ridges 5h protruding inside the clamp portion 5a. When the cover 1 is further lowered in this state when the piece 1c is positioned, the secondary positioning of the cover 5 with respect to the bottom case 1 is performed by the guide protrusion 5h, so the cushion attached to the inside of the cover 5 The position of the pressing portion 4g of the member 4 and the position of the wafer support groove 3e of the opening leg portion 4i are exactly the same, and the outer peripheral edge of the semiconductor wafer 10 and the orientation flat 10a portion are in the V groove 4f and the wafer support groove 4j of the pressing portion 4g. Inserted.
[0035]
When the cover 5 is further lowered in this state, the locking piece 1c on the bottom case 1 side is fitted into the locking hole 5g of the clamp portion 5a, and the cover 5 is locked to the bottom case 1. Even when the both side guide portions 5j of the clamp portion 5a are guided by the gap 1e of the skirt portion 1d, the cover 5 can be accurately fitted to the opening portion 1a of the bottom case 1 at a predetermined position.
[0036]
In the state where the cover 5 is locked, the semiconductor wafer 10 is pressed against the wafer support groove 3e by the elasticity of the arc-shaped portion 4d of the wafer pressing member 4c of the cushion member 4. On the other hand, the semiconductor wafer 10 does not rattle and a rotational force acts on the semiconductor wafer 10, and even if the orientation flat 10 a portion deforms the open leg portion 4 i, the reinforcing rib 4 k causes the open leg portion 4 i to deform. Therefore, the orientation flat 10a can be prevented from rotating over the leg 4i.
[0037]
【The invention's effect】
As described in detail above, since the cover can be removed from the bottom case simply by removing the clamp portions provided on both sides of the cover, the cover can be easily attached and detached. It is easy to operate.
Also, when removing the cover, the clamp part can be removed simply by pulling the clamp part outward while pushing the locking piece through the locking hole of the clamp part. When the cover is fitted into the opening of the case, the cover is positioned with respect to the bottom case at at least two locations: the guide rib protruding from the inside of the cover and the guide protrusion protruding from the inner surface of the clamp. The cover can be accurately fitted at a predetermined position of the bottom case.
As a result, there is no gap between the bottom case and the cover, so that the inside of the container can be reliably sealed.
Furthermore, since the outer peripheral edge of the semiconductor wafer is pressed from above by the wafer pressing member of the cushion member provided inside the cover, the semiconductor wafer will not rattle even if vibration or impact is applied during transportation. By fitting the orientation flat part of the semiconductor wafer into the wafer support groove provided in the open leg, it is possible to prevent the semiconductor wafer from rotating during transportation. There is no worry of causing this. In addition, even if a large rotational force acts on the semiconductor wafer, the reinforcing rib prevents the opening leg portion from being deformed, so that there is no possibility that the orientation flat portion gets over the opening leg portion and rotates.
